Design of Logical Analysis Apparatus Based onLabWindows/CVI and EDA's Technology

This paper points out that the conventional structure of Logic Analyzer is complex and the cost is comparatively high.It also introduces the designing ideas and methods of Virtual Logic Analyzer based on LabWindows/CVI and EDA's Technology.The Logic Analyzer not only expands the ability of analysis and calculation,but also strengthens the instrumental general use,thus lowering the cost of the Logic Analyzer.The paper mainly expatiates on the design of the hardware circuit and the software in the Virtual Logic Analyzer based on LabWindows/CVI and EDA's technology.
